The quality of the male semen directly affects the economic benefits of the farm.With the increase of age,the old male cocks will have a decline in reproductive performance such as reduced sperm collection,sperm motility and density.Direct elimination will affect the cost control and breeding management of the farm.Therefore,how to improve the breeding management or develop new feed additives to improve the breeding performance of male cocks,reduce the elimination rate,and extend the use period has become a problem to be solved in poultry farming.Some research reports have shown that lasia spinosa has an obvious androgen-like effect on male mice,but the effect on male cocks is still not clear,so it needs to be verified by experiments.In the experiment,24 450-day-old male cocks were randomly divided into a control group,1%,2%,and 3% test groups,6 in each group.The control group was fed with rooster feed,and the 1%,2%,and 3% test groups were added 1%,2%,and 3% lasia spinosa powder to the rooster feed,respectively.On the 0th,30 th,60th,and 90 th days,the body weight,sperm collection,sperm density,sperm motility,and testosterone content were tested and compared,and the fertilization rate of different groups of roosters was tested.Finally,the maleswere slaughtered and the testes were taken for testing The weight,the HE test of the testis was made into slices,and the seminiferous tubules were observed to analyze the effect of lasia spinosa on the reproductive performance of the rooster and provide guidance for poultry production practice.The main findings are as follows:The main research results of the paper are as follows:1.In order to detect the active steroid components in lasia spinosa,this experiment collected fresh roots of lasia spinosa for testing,and compared them with soybean,corn and feed,respectively,and found that the stigmasterol content of lasia spinosa sterol is rich,19.47±1.58 mg / 100 g.2.In order to study the effect of lasia spinosa on the quality of rooster semen,this experiment tested the sperm collection,sperm density and sperm motility of the test group and the control group.The test data showed that on the90 th day,the sperm collection,sperm density and sperm motility of the 1% and2% test groups were significantly higher than those of the control group(P<0.05).Tests have proved that lasia spinosa can effectively improve the quality of rooster semen.3.In order to study the effect of lasia spinosa on male fertilization rate,this study conducted artificial insemination test according to 20 hens per group of males.The test data showed that the fertilization rate of the 1% and 2% test groups was increased by 5.53% and 4.09% compared with the control group,and the fertilization rate of the 1% test group was significantly higher than that of the control group(P<0.05).Tests have proved that lasia spinosa caneffectively increase the fertilization rate of artificial insemination of roosters.4.In order to study the effect of lasia spinosa on spermatogenesis,the test was performed on the 90 th day,and the males were sacrificed and their testicles were taken out and weighed,and the testis sliced,and the diameter of the seminiferous tubules was stratified.The results showed that the testis mass in the1% test group was significantly greater than that in the control group(P <0.05);the diameter of seminiferous tubules in the 2% test group was significantly greater than that in the control group(P <0.01).Tests have shown that the active substance of lasia spinosa may promote spermatogenesis,thereby improving the quality of sperm and sperm vitality of the rooster.In summary,the root of lasia spinosa is rich in sterols.Adding lasia spinosa to the rooster diet may promote the occurrence of sperm,improve the vitality and production of the semen of the rooster,and thus improve the reproduction performance of the rooster.
